As China and Central and Eastern European countries see substantial potential for cooperation in nuclear power technology, China General Nuclear Power Corp, China's largest nuclear operator, is eyeing the region as a potential destination.

"CGN has always focused on the markets in Central and Eastern Europe," Huang Xiaofei, a spokesman for CGN.

"As we are bringing the Hualong One third-generation reactor technology to the UK, we are confident the technology could be applied in Central and Eastern European markets in the future," Huang said.

The United Kingdom's approval of CGN's technology will open the door to other European countries as the UK's appraisal regime is considered to be the strictest in the world, he said.

The company has been active in the Central and Eastern European nuclear markets considering the growing share of clean energy in the region.

It has signed memorandums of understanding with Czech and Romanian engineering companies for nuclear energy cooperation, and is in talks to build Poland's first nuclear power station.
